Application tiled July 21, 1913. Serial No. 780,230.

l 'o all whom. it may concern Be it known that we, (l1-nieren ALLEN MEL- mxonn, HERMAN Renn HARRIGAN, BENJA- MIN DENVER CorrAGn, HARVEY GnnnNLnAF McDownLi., and JOHN W'annnn Vennen, ot' Wilmington, Delaware, and CHRISTOPHER JonN Srnonni., of Elsmere, New Castle county` l')elaware, have invented a new and useful Improvement in Paper-Making Ma chines,' which invention is fully set forth in the following specification. This invention relates to the l"ourdrinier part of paper makingr machines, and particularly to the type ot machines in which provision is made for a considerable vertical adjustment of the forward or outer cud oi the Fonrdrinier part to tilt the saine to different angles with. relation to the horizontal, the desire as to the exact angle ot tilt varying with different paper manufacturers. The objects generally and principally are to provide a rigidadjustable base trame or beams. upon which the shake-iframe or ser tion is mounted to be laterally vibrated or slinken without also shaking said basetraine and other parts (euch afs the savealle` and their associated roofs) which do not .require shaking; to provide as'tructure in which the save-alle and their associated roots are mounted. on said base-frame, so

`that they participate in the vertical adjustn ment and therefore do not interfere with and restrict a considerable adjustment; to provide such a structure in which the entire beseft-ame. as well as the shake-frame, more particularly the rails thereof, and other parts mounted on said basefraine, pivot about a single common axis in thc vertical `tilting adjustment of said parte.' thereby avoiding strains and stress upon joints; to provide a connection between `the shake` 'l'rainc and the means 'tor 'vilfmating the saine that will aliord a range of adjustment cornnlcnsurate with the considerable vertical :uljustnient of which the forward ond ot the lfourdrinicr part susceptiliilc: and to automatically adjust thc height of the apron ot :he {low-boi: through connectionsto thc lor wurd end of the basefrauie. These and other objects apparent. from thc detailed' I;lc;-=cription are .ficcmnplishc'tl by thc struclurr el' thisl invention, a pref erred embodipanying drawings, wherein- Figure 1 is a side elevation showing particularl'i,r the Fourdrinier part of the ina-- chine; Fig. il' a side elevation of the shake Patented Nov. .2i/i1., 1914.

The shaklng-section or shakc-fra1ne of ,the machine includes a pair of longitudinal side rails o. the inner ends of which may be supported in any 4au-utable manner. In

the construction shown (see particularly` l? G and 7) thc machine-frame on cach .ll t) sido of the niachineis recessed to foi-in a C manner to he hereinafter described. to have a vertical adjustn'ient at their other or lor ward ends. the sujijiorts S duringl euch adiustnient turning on thcliolls S) :is pivots.

.ln other words, thc shake-traine ot which rails C are part) may be tilted on the horizontal axisof bolts 9.

ln order to provide for the lateral movement of the rails 6 :reduced by the usual vibration of the slia ing-section, the rails are preferably pivotallyV connected to the supports 8. As shown, the top tace of each block 8 is provided with an upwardly projecting circular boss 10,*,which engages a counterpart recess in a cappiece 11. This cap-piece 11 is formed withacircular boss 12 which engages a corresponding circular recess in the underside of the end of its rail 6. A bolt 13 iastens each rail 6 to its cappiece 11. By the construction which has just been described, it will. be seen 'that cach of the rails G 'is so supported as to bi capacitated to receive a vertical nioveniciit and horizontal shaking moven'ient.

rlhe outer ends of the side rails (5 are con nected by a frame which preferably consists of a U-shaped casting 14:, similar to that shown and described iii Patent No. 635,511, granted to Thomas ll. Sai/'ery October 24, 1899. The connections between the ends of the rails and the ends of the casting may be efi'ectod in any suitable manner; as illustrated, particularly in Fig. 5, the upper ends of the U-shaped frame are formed with sockets 15, in which arev mounted headedsleeves 16. A cap 17 Afits v'over the headed end of 16, and a' circular boss 18 on the cap fits a dcpressiononth'e'underside of the end of rail 6. A ,pin 19cm the cap engages a socket in therail and' prevents relative turning othese parts. The parts of the structure may be tied together in anysuitable Y manner. As shown, 'long bolts 20, 20, are

employed, one iiteach end of frame Mpass ing through rail 6, cap-17, sleeve 16 and frame 14 withja nut on. its lower end.

The Ushapedframe 14 is provided with suitable bearings for the breast-M1121. 'n the construction shown (see Figs.A 1 and 5),

these bearings are formed by vertically adjustable brackets 22, each resting against an adjustingscrew 23. g

In order to stiften the'shalring-seotion and particularly the rails 6 thereof, suitable struts 24, 24 are employed, one for each rail" (see Figs. 1 and 2), each strut being corinecterl at one end to the inner end of itsv rail 6 with an. interposed block, and at its other or outerend to the Ushaped frame 1.4.

t said outer end each strut is riveted to the angc 25- of a sleeve 26 which latter iii s into aiecess 2T (see Fig. 5) of the frame 14 and i vis therein traversed by bolt 20. To further titi lziizaclret arms 31' (see Figs. 1 and 9). The

plates 30 ofthe two rails 8, 6, support the audace bearings for the opposite ends ci' table-rolls 32, over which runs the usual Fourdrinir or making-wire 33.

Any suitable'means may be eniployedi'or vibratin the shaking-section, but the connection from suchmeans t9 said shalzingssection is preferably that hereinafter described. To assist the shakingmc'tion, vand also to cushion the stopping of the shaking-section at each end of its vibration, We provide two' coi-led springs 35,- 35^,each housed in'a telescopic casing comprising aiixed' cup-like part 36 and a movable eup -likel-part 37, with the ends of thc spring bearing against the bottoms ci cup-like parts.' The twosprings. and their cupelike casings are'strimg upon 4 and supported by a'. rod 38 mounted in bracket arms on the machine base. AL forked' bracketarm 3S) depending from Ushaped casting levembraces rod 38 between the ends of tbetwo movable parts 37, 37,'of the telescopic casings. The slot of the forked a'rrn4 39 elongated to allow'for a considerable vertical adjustment otthe outer- 'end of 4the shaking section without 'di'sengaging'said fork from the rodjBB and from between the casing parts 3l', 3.7.

lln general, the-constructionofthe parts heretofore described in detail and of other parte, such as the declrlestraps' 105 (only l' one of. which shows in Fig.` and'` wash" troughs 106, one for each strap', i-ssuch as-is well-known 4and disclosed in prior patents.

The improvements constituting' thelgpresent invention reside in' parts about" to be described. I

40, 1-1, are two beams preferably -I--beams i .base-frame and also the shakeframe pivot inthe tilting thereofy (and parts mounted thereon.) to vary the inclination driner part of the machine. At its other outer end the base-frame is suspended by means capable of a considerable range of vertical adjustment.

As shown in Figs. 1 and 3, the beam'fl() has a forked extension 7 0 embracing a vertical standard 71 and a block '72 movable vertically between guiding surfaces, of said standard. Two links 7 3, 73, pivoted at .their upper ends on opposite sides of blocr 7 2 and of the Fourat their lower ends to the two arms', respectively, of the extension piece 7i), .suspend beam 40 from said block 72. By similar construction, beani 41 is suspended trom a'blocli;

.quete and satisfactory.

ing crank-inn (or equivalent) not shownl in man or connewinff rod 90 is su) )orted bi and works in o bearing 91 on a. standard 9:2

' et the side of the machine. The rod. is sufficiently {lexible and lies sufficient play in bearing-91 to allow for slight sidewise movement imparted to its outer end by the driv the drawing-s. At its inner end pitman 9() has sliding' eonnection with the shake-frame in the 'forni oi' a collar 93 movable along a slightly curved rod Sl clamped at its ends in split lugs 95 and 96 on the Usheped cast# ing 14; of the shake-treme. rEhe curvature i of rod 94 is upon an are having its'eenter in the axis (ol the pivot bolts 9) on which the base-frame turns." lt follows that any "change in the inclination of the base-frame and part'- hereon will simply vcause the vrod t illto move in the 'collar atthe 4inner end ol pitnian 90, Without the imposition of any strain on the connection due to such clninge of inclination or adjustment.
